MACHINE FOR DRESSING STAVES FOR BARRELS, CASKS, 86o.

Specicaton of LettersPatent No. 2,652, dated May 30, 184:2; AntedatedNovember 30, 1841.

Be it known that I, SAMUEL LEARNED, of the town of Ridgeway, in thecounty of Orleansrand State of New York, have invented a new and usefulMachine for Dressing Staves for Hogsheads, Barrels, and otherCasks,which I call the Stavo-Dressing Machine and I do hereby declarethat the following is a full and clear description of the same and ofthe construction and operation thereof, reference being had to" theannexed drawings, making `part of this specification, and forthe "betterunderstanding the construction of the saidmachineand the manner of usingit I hereby givela description ofone which I have put in operation. lFigure l in the drawings is an eleva-tic of one side of the machine; AA, two of the principal posts tenoned intothe` topplate B three inchesfro-ni each end, D longitudinal girt teiioned intothe two posts A Aeighteen4 inches below the shoulders, which with the-top pla-te B holdsthe frame together' longitudinally.

E is a `standard tenoned into the girt D l and the top plate B threefeet three inches from the front post, to support the shaft of the bandwheel, E. There are two such frames placedotwo feet apart, connected atl the front end by the crossgirt, ,tenoned into the posts above thelongitudinal girts D and by one of the cross girts, c, which is boltedto the top plate Bivith` screw bolts; and the back end of the two framesare connected by the cross girt, a, beingtenoned into the `longitudinalgirts D nine inches from the outside of the posts A and by the crossgirt, e, bolted on the top plates B directly over the cross girt, a. Tothe two l lost mentioned cross girts, a and c, the head block, O, whichholds the knives and springs, is fastened by two strong screw boltsdirectly in front .of the receiving box Gr, the head block is four feetlong, with a piece tenoned into the back of each end in order to givelength to the springs N as a represented in side view Fig. 1 on the headblock directly in front of the receiving box or groove,'K. `The knives Mare fixed which `shave or dress the staves; said knives are portions ofa circle about one-third larger than the diameter of the casks for whichthe staves are intended, and are made fast to the head block by the backscrews PvP, which screws have a square eye to receive the ends of theknives; there are two small through the head block in `the rear of the1knives to4 permit the staves to pass through after they are shaved.

Directly in front ofthe knives are placed two rollers, L, in an uprightposition as `shown in side view Fig. l which receive the staves andguide them to thecutting edge of the knives; jsaid rollers `are threefeet four inches long with bands around and iron gudgeonsin each end,and runin` wood or instal boxes; said boxes are four inches long; onthe'middle of said rollers there is a wide band of iron to prevent thestaves fioin wearing the rollers; said rollers are three inches from thehead block; saidrollers and boxes are kept from moving up or down by twopieces of boards, fastened to `the upper and lower ends of the headblock as 4shown in side view Fig. 1; t-lie rollers and boxes are kept intheir proper position transversely by four strong springs of wood orsteel bolted to the side of the head block O at the upper and lowerends; these springs press the boxes together and consequently therollers, so that when the staves is propelled forward between them theyrecede from each other and accommodate themselves to the thickness ofthe` staves, and keep them in their proper position to be sha-ved by theknives; between the rollers and the knives are placed ltwo fenderboards, b as shown in side view Fig. 1 to prevent. the shavings fromwinding around the rollers; said boards are fastened to two small piecesof joists and one of said joists is .fastened to the top plates B andtheother to thelongitudinal girts D; said board are about. six inches apartin the centerwith their inside edges made bevel and stand close to therollers.

G, the receiving box with a groove K, to

receive and guide the rough staves 'and l guide the slide, H, and rack,I, is eight `feet- A gudgeons formed on each end which rests sol on theupper side of the longitudinal girts, l); the front end rests on thecro-ss girt, a, and on the upright stud which forms part of the lever,T, as the box vmoves up and down; at the front end it is kept in. theproper position by the upright guide, F,

and a small guide fastened to the inside of the post, as shown in theend view, Fig. 3, the groove K is five inches deep from the back end tothe pinion, and the remainder is three inches deep as represented inside Vview F ig. 1g in the bottom of YVsaid groove there arefive'friction rollers, as shown in view F ig., 2 'to' reduce theyfriction of the slide, H, one of the rollers is under the center'of thepinion;y said rollers are iron with receiving box is fixed a strong ironstirrup or staple, V, as shown in the end view Fig. 3, and on the uppergirt, C, is fixed a strong steel spring catch, U, as shown in end viewFig. 3 to receive the stirrup or staple, V, so

that when the front end of the receiving box is raised the spring latchholds it in that position until it is ldisengaged by the guard W, whichis hereafter described.

H, the slide on which the rack, Iguard,

W, and the follower, it, is fixed, as represented in view Fig. 1 andFig. 2 the slide is eight feet six inches long two by three, the rack Iisfour feet long and is bolted firmly on the upper side of the back endof said slide, there is a plate of band iron four feet long on the underside of the back end of the slide to prevent wear by the frictionrollers, on the back end of the slide thereis lstrap of iron two incheswide and one half inch thick and long enough to lap over the under andupper sides of the slide and rack two inches in order to have the screwbolt, L, pass through, to firmly bind the strap of iron over the backend of the slide and rack, which forms a follower, 7L, as shown in viewFig. 2 which comes in contact with the staves; and by means of thefollower being raised above the rack so that when the rack is disengagedfrom the pinion and the slide is drawn back by the weight, Z, it comesin contact with the plate of iron, g, across the receiving box whichstops the follower from being drawn back under the pinion by the weightZ, near the front end of the slide H is fixed the cam piece or guard, W,as shown in side view Fig. 1, so when the rack is thrown into gear withthe pinion the slide is carried forward propelling the stave before ituntil the guard W, comes in contact with the spring catch, U, which isthereby disengaged from the stirrup or staple V, and the receiving boxfalls down and disengages the rack from the pinion and the counterWweight Z, falling draws the slide back ready to receivel another stave,the above mentioned weight Z is attached to the under side of `the slideH, by the leather strap Y,

which passes over the pulley fixed in the stud, X,-as shown in view Fig.V1.Y The Y `said lever is connected to the cross lever, T,

and the long end is pressed down by the `foot of the attendant as shownin side view Fig. 1.

T, cross lever three feet six inches long with a stud and braces tenonedinto the upper side to raise the receiving box, the back end of saidlever is fastened to theI front post A by an iron pin and the other endis fastened to the short end of the lever, S, by a swivel bolt as shownin end view Fig. 3.

E band wheel six feet diameter and one. foot wide fastened on the shaft,d, said shaft is made of iron three inches square with journals onV eachend which run in metal boxes fixed in the wheel standard E.

J, pinion eight inches diameter fastened on shaft, d, as shown in viewFig. 2.

The operation is as follows: A leather band or belt from any suitablepower, giving lthe band wheel E, about forty revolutions per minute, theattendant puts a stave into| the receiving box, or groove K; and pressesdown the lever S with his foot, thereby raising the receiving box andthrowing the rack into gear with the pinion, the stave is therebypropelled forward between the rollers| and the knives, until the guard,W, strikes the spring catch, U, which disengages it from the stirrup orstaple V, and the receiving box falls, throwing the rack and pinion outof gear, and the counter weight Z, falling,.-

draws back the slide ready to receive another stave.

I am aware that machines have been made for dressing stoves by forcingthroughA between knives by a follower operated by al rack and pinion,and I do not therefore claim this as of my invention; but

What I do claim as my invention and desire to secure by Letters Patent,is-

1. The arrangement for throwing the rack out of gear by having thereceiving boX in l for thepurpose of throwing the rack into which theslide Works hung at one end by a gear as herein described. joint or rolland the other provided With a Sept. 15, 1841.
